FreeAgent Referrer Code Competition

/**
 * tl;dr - https://twitter.com/jamierumbelow/status/425274669152079872
 * 
 * The Story:
 * 
 * I posted a message on Twitter asking if anybody used FreeAgent, and if they had a referral code.
 * Upon referring a new customer, both you and 'the referred' get an lifetime discount.
 * 
 * I receieved five replies almost instantaneously, from @chadtomkiss, @_beneverard, @IainMcPherson,
 * @wolfl and @spamoom. Thanks guys!
 * 
 * As I didn't want to show favouritism, I thought I'd write a quick script to pick, at random, a person
 * from whom I could accept the referral code.
